The Warning Decision Support System -- Integrated Information (WDSS-II)
is the second generation of a suite of algorithms and displays for
severe weather analysis, warnings and forecasting. WDSS-II has been
developed jointly by engineers and scientists at the National Severe
Storms Laboratory (NSSL) and the Cooperative Institute for Mesoscale
Meteorological Studies (CIMMS) at the University of Oklahoma.

WDSS-II has three components:

A suite of multi-sensor automated weather algorithms
including techniques for combining and interrogating radar data,
diagnosing hail, lightning and precipitation.

A 3D earth and time-centered display for viewing
multi-sensor
data and algorithm outputs.
